Response of palila and other subalpine Hawaiian forest bird species to prolonged drought and habitat degradation by feral ungulates
Extinction has claimed half of all historically-known Hawaiian passerines, and today many extant species are increasingly threatened due to the combined effects of invasive species and climate change. Habitat disturbance has affected populations of feeding specialists most profoundly, and our results indicate that specialists continue to be most vulnerable, although even some abundant, introduced,

2011 Kiwikiu (Maui Parrotbill) and Maui 'Alauahio abundance estimates and the effect of sampling effort on power to detect a trend
The Kiwikiu (Pseudonestor xanthophrys), also called the Maui Parrotbill, is an endangered,
forest bird found only in high elevation, wet forest of the eastern portion of Maui Island. Recent
surveys, conducted at five year intervals, have revealed wide variation in abundance estimates
(Camp et al. 2009). Effective management and conservation requires accurate estimates of
abundance, which is di

Developing accurate survey methods for estimating population sizes and trends of the critically endangered Nihoa Millerbird and Nihoa Finch.
This report describes the results of a comparative study of bird survey methods undertaken for the purpose of improving assessments of the conservation status for the two endemic passerines on the Island of Nihoa—Nihoa Millerbird (Sylviidae: Acrocephalus familiaris kingi) and Nihoa Finch (Fringilidae: Telespiza ultima; also referred herein as millerbird and finch)—both listed as endangered under t

Birds in Hawai'i Volcanoes National Park: Summary of the 2010 inventory and monitoring program survey
The National Park Service (NPS) created the Inventory and Monitoring (I&M) Program in 1998 to establish baseline information and assess long-term trends in "vital signs" or key abiotic and biotic elements of National Parks (Fancy et al. 2009). The Pacific Island Network of the I&M Program developed a Landbirds Monitoring Protocol (LMP; Camp et al. 2011) to estimate species-specific status and moni

Bird populations on the Island of Tinian: persistence despite wholesale loss of native forests
Bird habitat on the island of Tinian, Mariana Islands, has been substantially altered, and only around 5% of the island has native forest today. The modern bird fauna is likely to be a subset of the original avifauna where only species tolerant to native forest loss and human disturbance have survived. Avian surveys were conducted on the island in 2008 by the U.S. Fish and Wildlife Service to prov

Status and trends of the land bird avifauna on Tinian and Aguiguan, Mariana Islands
Avian surveys were conducted on the islands of Tinian and Aguiguan, Marianas Islands, in 2008 by the U.S. Fish and Wildlife Service to provide current baseline densities and abundances and assess population trends using data collected from previous surveys. On Tinian, during the three surveys (1982, 1996, and 2008), 18 species were detected, and abundances and trends were assessed for 12 species.

Reoccurrence of 'Ōma'o in leeward woodland habitat and their distribution in alpine habitat on Hawai'i island
The endemic solitaire, 'Oma'o (Myadestes obscurus), is common in windward forests of Hawai'i Island, but has been historically extirpated from leeward forests. The last detections of 'Oma'o on the leeward side of the island were in woodland habitat on the western flank of Mauna Loa in 1978. 'Oma'o were detected in woodland habitat in relatively low densities during a 2010 forest bird survey of Haw

Palila abundance estimates and trend
The Palila (Loxioides bailleui) is an endangered, seed-eating, finch-billed honeycreeper found only on Hawai`i Island. Once occurring on the islands of Kaua`i and O`ahu and Mauna Loa and Hualālai volcanoes of Hawai`i, Palila are now found only in subalpine, dry-forest habitats on Mauna Kea (Banko et al. 2002). Previous analyses showed that Palila numbers fluctuated throughout the 1980s and 1990s b

Temporal variation in bird and resource abundance across an elevational gradient in Hawaii
We documented patterns of nectar availability and nectarivorous bird abundance over ~3 years at nine study sites across an 1,800-m elevational gradient on Hawaii Island to investigate the relationship between resource variation and bird abundance. Flower density (flowers ha-1) and nectar energy content were measured across the gradient for the monodominant 'Ōhi'a (Metrosideros polymorpha). Four ne

Design of forest bird monitoring for strategic habitat conservation on Kaua'i Island, Hawai'i
This report was commissioned by the U.S. Fish and Wildlife Service (USFWS). The purpose was to develop a monitoring program for Kaua`i forest birds in the USFWS Strategic Habitat Conservation and adaptive management frameworks. Monitoring within those frameworks is a tool to assess resource responses to management and conservation actions, and through an iterative learning process improve our unde

Forest bird monitoring protocol for strategic habitat conservation and endangered species management on O'ahu Forest National Wildlife Refuge, Island of O'ahu, Hawai'i
This report describes the results of a pilot forest bird survey and a consequent forest bird monitoring protocol that was developed for the O'ahu Forest National Wildlife Refuge, O'ahu Island, Hawai'i. The pilot survey was conducted to inform aspects of the monitoring protocol and to provide a baseline with which to compare future surveys on the Refuge. The protocol was developed in an adaptive ma
